The present invention refers. to an arrangement for automatically lighting and extinguishing lighting fixtures at predetermined times, the releasing apparatus beand the Like, of which the following is a ing regulated automatically according to the length of the day,- the latter feature being considered as a known one. L

In the accompanying drawing a mode of carrying out the invention is exemplified, Figure 1 being a front View of the arrangement, and Eig. 2 giving a longitudinal section through the same, Figs. 3-6 giving any deta l ls. "The shaft 1 'is driven by say a clockwork in the direction of the arrow in known manner so that it makes one revolution in'an hour. The same as in other clockworks on shaft 1 a sleeve 2 is fitted, which carries a toothed 'wheel '3 and a. hand 4. Sleeve 2 is clamped to shaft 1, so that the-hand at-' tached to said sleeve will likewise make one revolution in an hour. The toothed wheel 3 is coupled by means of the intermediate gears 5 and 6 with wheel theratio of the transmission being such, that this wheel completes -one revolutionjn twenty-four hours. Wheel 7 is coupled rigidly with the forward disk 9 by means of a rigid sleeve 8 so that said disk will also complete one revolution per day. I

On sleeve 8 turns loosely a disk 10, which is carried along by the disk 9in front of it by means of a screw 11. Behind disk 10.

an eccentric 12' is arranged loose on sleeve 8, but rigidly coupled with the toothed wheel 13. 'The latter again is coupled by means of the two intermediate gears15.and 16, which are fitted on the shaft 14. attached to disk 10, withthe gear wheel 17 likewise arranged on disk 10, and the shaft of whichcarries a cam-wheel 18. The eccentric 12 is thus driven'from the disk 10. v

On the forward side of the rigid part-ition 19 is arranged a pin'20 (shown in Fig.

2 below by dotted lines) which pin projects so far, that the cam-wheel 18 will strike against it with its cams and will be turned so far that at the next passage the other cam will engage therewith.

On the front of disk 9 two slides 21 and 22 are adjustable in a rectilinear manner, the one end of which slides is guided by means of a sloton pins 23 and 24 respectively fittedin disk 10, the other ends being" bent'at right "angles 25 and 26 respectively passing through slots provided in the disks 9 and 10 rest on the periphery of the eccentric 12 arranged behind disk 10. -Each of the said slides 21 and 22 has an arm 27 and 28 respectively, which may be adjustable on its respective slide, these arms however being shown in the drawing as if made in one piece with the said slides.

In frontof disk 9 and loose on sleeve 2 are arranged arms 29 and 30, said arms having slots 31 and 32 respectively in which pins 33 and 34 are adjustable by means of screws. These .pins project toward inside so far, that they are carried along by the arms 27 and :28 of the slides 21. The arms 29 and 30 are made of two parts, so that their outer sec- 'tions 35 and 36 swivel around the coupling screws 37 and 38. These outward sections are bent over inward, so that on the' arms 29 and 30 revolving, they will move the lever 39' and thereby turn the shaft 40,-the front set'oif end of which is guided in the dial-flange 41 and fitted witha hand 42.

The other end of this shaftpenetrates the rlgid partit1on'l9 and terminates in the release lever 43.

The disk 9 completing its revolution once every twenty four hours carries'a-hand 44, projecting over the dialwflaizge 41 and also longer and ,wider radial slots than the loose disk 10 behind itand also a slot parallel to its periphery, in which-slot moves the screw .11 coupling the two disks.

The new arrangeme'nt operates as follows? When shaft l-is revolved once in an hour, the hand 4 will likewise pass once around the flange-dial 41, and indicate the minutes, the same'like a minute hand of a clock. The disk will complete one revolution in twenty four hours and indicate the hours with its hand 44. the same as the hour hand of a clock, if the flange-dial is provided with a twenty four hour graduation. In Fig. 1 the Roman figures indicate the hours of the day, the Arabic figures thoseof the night. The clock in the drawing is showing the time as 11.57 a. m, Of the two arms 29 and 30, the arm 29 serves for lighting and arm 30 for extinguishing. .The figures marked on disk 9 give underthe lighting arm 29 the P. M. hours, and under the ei; tinguishing arm 30 the A. M. hours. As shown in Fig. 1 the arrangement is set for lighting up at 3.35 p. m. and extinguishinp at 7.50 a.-m. If now the disk 9 and witn it arms 29 and 30 are revolved, the lighting arm 29 will on the hand 44 reaching the time 3.35 p. m. turn the lever 39. By the thereby effected revolution of the shaft the release lever 43 will in known manner release a spring, which will thereby open say a gas-valve, close an electric circuit or do some other work of thekind. When the hand 44 has advanced as far as the time 7.50 a. m. the extinguishing arm will by turning, lever 39 cause the reverse action, so,.

say, the closing of the previously opened gas-valve. The four-pronged cam-wheel 18 will pass within, every twenty four hours once the stationary pin 20 and be given by the same a quarter turn; The wheel 17 fitted on the shaft of the cam wheel 18 has 8teeth and meshes with wheel 16 which has 38 teeth. The wheel 15 fitted together with wheel 16 on shaft 14 has 9 teeth and meshes with the wheel 13 attached to the eccentric 12, said wheel 13 having 173 teeth. By this gearing the eccentric will after days complete one revolution to disk 10. At the time time, the'slides '21 and 22 will carry mt a reciprocating motion, by their ends 2!? and 26 resting on the periphery of the eccentric, whereby the lighting and ex; tinguishing arms are also given a corresponding travel over the disk 9.

The outward shape of the eccentric 12 is made accordingto the annual light diagram, so that the shortest radius vector corresponds with the shortest distance of the slides from thecenter, and the largest radius vector represents the largest distance of the slide ends from the center. .The increase and decrease of the intermediate radiivectors during the daily rotation of the eccen trio are ofthe same proportion to each other as the increase and decrease of the sine of the corresponding angles, which are inclosed by the release lever and an imaginary abscissa-axis at the daily movement, if

29 and 30 will receive a daily adjustment, which corresponds to thegvariation oi the time of the sun-rise and sun-set. As however accordingto astronomical charts for the sun-rise and sun-setthe time for the earliest lighting up is ahead of the tizne for the earliest extinguishing by one" half year and three days, and the time for the latest lighting up is ahead of the time for the latest extinguishing by one halfyear and six days, the ends 25 and 26 of the slides 21 and 22 are bent slightly aside (c'fr. Fig. 1 to the left), the end 25 however somewhat more than end 26, so that their points of contact with the eccentric are no morediametrical to each other in the line of the slots in disk 10.. As the eccentric rotates according to the relation between disks 9 and 10 toeach other, the suitable bending of the said ends 25 and26 will have the conseposition of the slide 21 (lighting up) I and the extreme outward position hf slide'22' (extinguishing) there lies a rotation of the eccentric equal to' one half year and three days, and a rotation of one half year and six days between the innermost positionof slide 21 (lighting up) and the innermost position of slide 22 (extinguishing).

If the pin, 20 is fitted. between the shaft 1 of the cam-wheel 18, and if the eccentric 12 shall turn like the hands of the clock to quence, that between the extreme outward disk9, the ends of the slides 25 and 26 must be bent to the right. As the new arrangement -mus t release according to astronomical time,

in order to work correctly at various places, and as there is a more or less great difference between ordinary time and astronomical time, the releasing mechanism has to be somewhat adjusted, said adjustment being effected in the present arrangement by loosening the screw 11 and advancing or re turning theloose disk 10 together with the entire releasing mechanism with respect to the hourdisk 9, whereupon the screw 11 is again tightened after completion of such adjustment. Further adjustments with respect to the local lighting up and extinguilhing time may be effected by loosening the screws 37 and38 and moving the outer sections 35 and 36 of the releasingarms 29 and '30 forward or backward as may be, and thereuponagain tightening the screws.

As the same days have varying lengths on different altitudes, longitudinal slots for the pins and 34 are providedin the arms 29 'and 30, so that after the respective screws have been loosened, the said pins may be set at greater or smaller distance from the center by adjusting them in the slots.

For northern altitudes the pins 33 and 34 should be moved toward the inside, for southern altitudes toward outside. The twilight lasls generally longer on the northern altitudes than on southern, wherefore 7 moving the outer end of the lighting up arm 36 backward. If this adjustment were only done to the lighting up arm, only the lighting up time would be advanced, Whereasthe lights would be extinguished everywhere at the same time. If the arrangement is to light up at different times, but to extinguish ata given hour, say mid-night, the slide 22 is removed, and the extinguishing arm 30 is moved beyond 12, whereas the hand 44 would have to be fixed in another manner thanshown in the drawing. The pin 34 of the extinguishing arm is then made so long, that it projects into a slot in disk 10, or disk 9 is provided with a rigid projection in the shape of the outward section 35 of the extinguishing arm. I v

If iii-lanterns with severalburners all are to. be lighted. at the same time, but only part of the burners or all but one shall be extinguished at a giventime, and this last one is to be extinguished at day-break, the arrangement is provided besides the movablearms 29' and- 30 with a rigid projection at midnight,, whereby three releases per day are obtained.

In order to allow of adjusting the eccentric according to the season, in which the,

arrangementv is employed, first, the shaft 14 is extended in front, so that it projects.be-. yond disk 9. At the end of this shaft is arranged a square end, onv which a spanner can be fitted, and the shaft be thuspositively turned. Thus the eccentric 12 can be moved forward orbackward as may be required,

and its position maybe controlled through the slots inthe disks}? and 10 and by the position of the slides 27 and 28.

Should the releases have been exchanged,

and say the lights be .extinguished when they should be lighted, separate releases may be effected by turning the release shaft 40 and thereby obtaining the release in the proper sequel. The'clockwork required to drive the arrangement is not shown nor described, as it may be considered as known. Also the engagement of the releasing lever 43 with the releasing gear has not been shown nor described, as such releasing gear may be made of. any design, say like the striking mechanism of a clock.
